I'm going to buy a code reader but when I looked for one all the ones said 1996 & latter for OBD2. My van being a 1995 I thought great OBD1 I can jump the A & B terminals to get the codes.
Having said this I went out to do this & yes my plug had 8 pins like the OBD1's closer look I saw the A pin but no B pin it was empty. Although she does not have 16pin plug & looks like an OBD1 plug it must have the OBD2.
My question is she is a 95 the plug looks like the OBD1 but no b terminal this must be an OBD2?
I just want to know so I can buy the right code reader.
OBD1 or OBD2 on 1995 Chevrolet Lumina APV
Yes it has the 8 pin ALDL the A pin is far right top row & the B pin should be next to it but there is no B pin it's empty.
I checked a code reader for OBD1 & whe you read what Chevrolets it checks in 95 the only one it read is the Caprice 4.3L as it said all other Chevys do not have the B pin cause GM changed the ECM so it can not read it! Crazy isn't it cause now I think the only way I could go would be to buy a code reader that checks both OBD1 & 2 @ $200. when the other was around $30.
